Fishery Collapse
Gwynne Dyer (channelling Prof. Boris Worm of Dalhousie University):
A major human food source — the principal source of protein for one-fifth of the human race — is going to collapse in the next generation unless drastic measures are taken. The world’s fishing fleet needs to be reduced by at least two-thirds, bottom-trawling must be banned outright, and widespread fishing moratoriums for endangered species and even for whole areas need to be imposed for periods of five or even ten years.
Unfortunately, the minimum measures needed to prevent ecocide in the oceans would cause major short-term disruption and throw millions out of work, so they probably won’t be taken. It will be much easier politically to ignore what is happening now and let the collapse happen later, on somebody else’s watch.
And governments worry about terrorism.
